Severs disease, also known as calcaneal apophysitis, is a condition in which the growth plate along the heel becomes inflamed. It most commonly occurs in active, early-teen children. Most patients with Severs disease complain of heel pain. In general the pain is exacerbated with increased activities, such as running, jumping, or climbing stairs. The pain often improves with a period of rest.
There are several theories as to the cause of this condition. These range from a tight Achilles tendon, to micro stress fractures of the calcaneal apopyhsis. The prevailing theory suggests that the condition occurs when the child’s growth plate is at its weakest. Combined with increased athletic activity, improper shoe gear and trauma the heel becomes inflamed and painful.
The symptoms of Sever?s Disease may vary but usually include generalised pain and discomfort around the back of the heel. Can be one sided or both sides. Starts after child starts a new sport season. May cause child to limp due to pain. Increases with weight bearing activity. Heel becomes red and can be swollen. X-rays are usually inconclusive and simply show the growth plate.
Sever condition is diagnosed by detecting the characteristic symptoms and signs above in the older children, particularly boys between 8 and 15 years of age. Sometimes X-ray testing can be helpful as it can occasionally demonstrate irregularity of the calcaneus bone at the point where the Achilles tendon attaches.
Non Surgical Treatment
Although most cases do get better on their own, recovery typically takes several weeks or months. Adolescents can continue to play sports if the activity does not cause discomfort, but staying active does prolong the recovery period without treatment. As a result, rest and avoidance of athletic activity is usually recommended, along with medication for pain and swelling.
Exercises that help to stretch the calf muscles and hamstrings are effective at treating Sever’s disease. An exercise known as foot curling, in which the foot is pointed away from the body, then curled toward the body in order to help stretch the muscles, has also proven to be very effective at treating Sever’s disease. The curling exercise should be done in sets of 10 or 20 repetitions, and repeated several times throughout the day.
